Keysight E4980B Precision LCR Meter 0.05% Accuracy 20 Hz-2 MHz 4-Terminal Pair USB LAN
Keysight E4980B Precision LCR Meter (20 Hz to 2 MHz)
The Keysight E4980B precision LCR meter is the current-generation bench instrument for accurate, repeatable impedance measurement of capacitors, inductors, resistors, transformers, and semiconductor components. Combining 0.05% basic accuracy, a wide 20 Hz to 2 MHz frequency range, and fast 5.6 ms measurement speed, the E4980B answers the demanding test needs of both R&D laboratories and high-throughput production lines.
Key Features
- 0.05% Basic Accuracy — dependable measurements across a wide impedance range.
- Wide 20 Hz to 2 MHz Frequency Range — covers low-frequency power components through high-frequency ceramic capacitors and inductors.
- Fast 5.6 ms Measurement Speed — maximizes throughput on automated production test lines.
- 4-Terminal Pair (Kelvin) Configuration — eliminates lead and contact effects for accurate low-impedance measurement.
- 201-Point List Sweep — single-point, auto, and list sweep modes for flexible device characterization.
- Built-in DC Bias — evaluate components under realistic DC bias conditions (0 to +/-2 V standard, up to +/-40 V optional).
- Comprehensive Parameter Set — |Z|, |Y|, C, L, D, Q, R, X, G, B, theta, Rp, Rs and ESR from one instrument.
- Intuitive 320 x 240 LCD Interface — clear readouts and straightforward front-panel operation.
- Flexible Connectivity — USB host/device and LAN standard, GPIB and Handler interface optional.
Typical Applications
- R&D and incoming inspection of capacitors, inductors, and resistors
- Production-line testing of passive components and materials
